2b525ff87e Ensure minimum kernel version for thin_ls 
Ensure that kernel >= 4.4.0 or RHEL/Centos 7 kernel >= 3.10.0-366 exists before starting the thin
pool watcher. Prior versions have a bug in which reserving and releasing the metadata snapshot can
cause thin pool corruption.

of whitelist envs to API

d0424eca0f Add --docker_only flag to enable tracking for only docker containers and root. 
This reduces unnecessary load on the system and also cleans up the UI clutter.
Currently defaulted to false.

9ce178f707 Lazily init DBus only when it is needed 
OpenShift has some cAdvisor packages in its import chain. The init() here
invokes Dbus start even when cAdvisor is not actively running or being
used (in our packages).  This change makes the systemd check and dbus
initialization and connection lazy, occuring only the first time someone
invokes UseSystemd().

a0a419614f Add /storage endpoint to 2.0 API. 
/storage returns {device, mountpoint, capacity, usage} for all filesystems.
In addition, it also detect and applies label for each filesystem - currently two - "root", "docker-images".

/storage/<label> returns info about the filesystem with specific label. eg. /storage/root returns info for root filesystem.
